I recently received a Dewalt DW718 that was giving to me by a buddy because it didn't work. I already have changed the brushes (nothing) and armature only because it was given to me. I need a little advise as far as what steps or what should I go about doing next. I really would like to get it going because I could put it to good use or sell it & try to make a little profit off of it. What do y'all think?
